Check Digit Verification of cas no

The CAS Registry Mumber 1093663-71-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,6,6 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1093663-71:
(9*1)+(8*0)+(7*9)+(6*3)+(5*6)+(4*6)+(3*3)+(2*7)+(1*1)=168
168 % 10 = 8
So 1093663-71-8 is a valid CAS Registry Number.

Controlling regiochemistry in the gold-catalyzed synthesis of unsaturated spiroketals

Paioti, Paulo H. S.,Ketcham, John M.,Aponick, Aaron

supporting information, p. 5320 - 5323 (2015/01/16)

A novel gold-catalyzed synthesis of unsaturated spiroketals that addresses regioselectivity issues commonly reported in metal-catalyzed spiroketalization of alkynes is reported. The reaction sequence is regulated by an acetonide protecting group which und
